Sample Solution:

SQL Code:

-- This SQL query calculates the count of penalty shots for each country participating in soccer_country.

SELECT a.country_name, COUNT(b.*) as "Number of Shots"
-- Selects the country name and the count of penalty shots for each group, aliasing the count as "Number of Shots".
FROM soccer_country a, penalty_shootout b
-- Specifies the tables involved in the query, using aliases 'a' for 'soccer_country' and 'b' for 'penalty_shootout'.
WHERE b.team_id = a.country_id
-- Connects rows in 'penalty_shootout' where 'team_id' matches 'country_id' in 'soccer_country'.
GROUP BY a.country_name;
-- Groups the results by the 'country_name' column from 'soccer_country'.

Sample Output:

 country_name | Number of Shots
--------------+-----------------
 Poland       |               9
 Italy        |               9
 Germany      |               9
 Portugal     |               5
 Switzerland  |               5
(5 rows)

Code Explanation:

The said query in SQL that retrieves the number of penalty shootout shots taken by each country.
This query counts the number of rows from the penalty_shootout table and the "Number of Shots" is used as a alias to the count result.
The join condition between the two tables, linking the team_id column from penalty_shootout with the country_id column from soccer_country.
The GROUP BY clause groups the results by country_name, so that the count is calculated for each unique country in the soccer_country table.
